A process for the reduction of carbon dioxide and carbonyl sulfide from various types of gas emitting sources containing carbon dioxide and/or gas or liquid emitting sources containing carbonyl sulfide, using ion exchange resin.

Process and apparatus for carbon dioxide and carbonyl sulfide capture via ion exchange resins

The present invention relates to a process for producing weakly acidic cation exchangers of the polymethacrylic acid type by alkaline saponification of a crosslinked copolymer of alkyl methacrylate and methacrylic acid.

Weakly acidic cation exchangers

Monodisperse cation-exchangers and anon-exchangers are conditioned by a process and thereafter used as catalysts and for the production of bisphenols.

Method for conditioning ion exchangers

Strongly acid cation exchangers with improved properties are obtained if the sulphonation of the non-functionalized polymers is carried out at a high temperature and/or in the absence of oxygen.

Process for the preparation of low-bleeding cation exchangers

Process for the removal of dissolved oxygen from phenol

A catalytic agent for etherifying, hydrogenating and isomerizing crude C.sub.4 -C.sub.8 -- hydrocarbon mixtures having a sulfur content, comprising a macroporous or gel cation exchanger having SO.sub.3 H groups and being charged with a mixture of a metal selected from the group consisting of Pd, Ru, Rh and Pt with a metal selected from the group consisting of Fe, Co, Ni, Cu, Ag and W.

Catalyst agent for etherifying, hydrogenating and isomerizing crude      .

Bis-hydroxyphenyl-n-alkanes are prepared by contacting dicarboxylic acids or dicarboxylic acid derivatives with fluorine-containing organic sulphonic acids, where appropriate with the addition of a phenolic compound, and converting the alkanediones, which are thus obtainable, into bis-hydroxyphenyl-n-alkanes by hydrogenation and, where appropriate, an additional ether cleavage. The invention also relates to new bis-hydroxyphenyl-n-alkanes and to new alkanediones.

Process for the preparation of bis-hydroxyphenyl-n-alkanes, new

The invention relates to SO.sub.3 adducts with imides, which are sparingly soluble or insoluble in water, of the formula ##STR1## in which R.sub.1, R.sub.2 and R have the meaning indicated in the description, a process for the preparation of the adducts and their use as sulphonating agents.
